现在各地都积极开展团体防痨检查,为了面向生产,把机器直接搬至工厂,有的还安装了X线流动检查车。如果是透视,因为用电量较小,无论大小工厂单位都能负担;但对萤光缩影检查,则往往有些单位发生困难。因为缩影的耗电量大,厂方电表不能负担或负担过重,以致造成缩影片曝光不足而影响诊断。我们采用了下述方法,解决了这个问题,茲特介绍如下,供同道们参考并望予以指正。一般应用的X线机都是220伏单相电流。然而有很多工厂,由于220伏单相电流仅供照明使用,因而电表不大,一般都是10至20安培。而萤光缩影的用电量,往往要超出20安培,以致不能使用。但是工厂在动力
At present, all groups are actively conducting inspections on flood prevention. In order to face production, the machine is moved directly to the factory, and some X-ray flow inspection vehicles are also installed. If it is perspective, because the power consumption is small, the factory unit can afford it. However, when it comes to the inspection of the fluorescent microcosm, it is often difficult for some units. Because of the large power consumption of the microcosm, the factory meter cannot afford or burden it too much, resulting in underexposure of the shrink film and affecting the diagnosis. We have adopted the following method to solve this problem. Zetter introduced it as follows for reference and hope to correct them. The general application of X-ray machines is 220 volt single-phase current. However, there are many factories, because the 220 volt single-phase current is only for lighting, so the meter is not large, generally 10 to 20 amps. The power consumption of the fluorescent miniatures is often over 20 amps, which makes it impossible to use them. But the factory is motivated
